Relevant Information:

Aquarium Care: Will need a large tank if keeping a few as they are territorial. Not to be trusted with smaller fish as they will undoubtedly be eaten. Provide hiding places large enough where they can rest upside down. May grow larger than the stated size of 30cm but this could take a few years to fulfill. Diet: Will eat most aquarium prepared foods such as flake, tablets, pellets, live and frozen. Unusual to this family is the ability of this catfish to swim upside down, which it does for 90% of the time.

Common Name:
